2GB (1GB 128M x 64-Bit x 2 pcs.)

PC2-6400 CL4 240-Pin DIMM Kit

DESCRIPTION:

Kingston's KHX6400D2LLK2/2GN is a kit of two low-latency 128M x 64-bit 1GB (1024MB)

™

DDR2-800 CL4 SDRAM (Synchronous DRAM) memory modules that are NVIDIA

SLI

Both modules are based on sixteen 64M x 8-bit DDR2 FBGA components. Total kit capacity is 2GB (2048MB). Each module pair has been tested to run at DDR2 800MHz at low latency timing of 4-4-4-12 at 2.0V. The SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-15-2T at 1.9V. Each 240-pin DIMM uses gold contact fingers and requires +1.8V. Modules are intended

™

SLI

for use with NVIDIA

certified solutions. The electrical and mechanical specifications are

as follows:

FEATURES:
